Kansas City (2021)
On 29 January 2021, Williams was announced as the head coach of the new expansion team Kansas City NWSL.[n 1][8][9] After one season as head coach he moved to a technical-staff scouting and talent identification role. The club went 3-14-7 in his lone year at the helm finishing last in the NWSL with 16 points.[10] Williams transitioned to a front office role with the newly-named Kansas City Current but was relieved of his duties by November 2022 following accusations of disrespectful and inappropriate conduct towards the team's roster which was later proved to be unsubstantiated.[11]
